{"product_id":"rki-air-alert-fixed-gas-transmitter","title":"RKI Air Alert Fixed Gas Transmitter","description":"\u003cp\u003eThe RKI Air Alert is a compact, wall-mounted fixed gas transmitter using electrochemical, infrared, or PID sensor elements to cover 50+ gases — from common toxics like CO, H2S, and NH3 to refrigerants, ozone, and VOCs. A clear polycarbonate window over 3-color alarm LEDs and an audible buzzer give local status at a glance, while both 4-20mA (3-wire) analog and RS-485 Modbus outputs integrate directly into a building automation or process control system.\u003c\/p\u003e\n\u003cp\u003eAvailable with a local LED\/buzzer display or a 2-relay configuration for direct alarm switching, and in a wireless, dual battery-powered version (Airlink Alert) that reports over a 900MHz radio link for installations where running wire back to a controller isn't practical. The NEMA Class I\/4\/4X\/6 polycarbonate enclosure is IP66, UL508, and UL746C(f1) rated for indoor or outdoor mounting — this is a general-purpose transmitter, not explosion-proof rated. The configurations listed here cover the most commonly ordered gas types and power\/connectivity options; additional gas ranges are available by quote.\u003c\/p\u003e","brand":"RKI Instruments","offers":[{"title":"CO 0-300 ppm, AC Power, Local Display","offer_id":48206570487998,"sku":"66-5A01-03-L","price":1147.5,"currency_code":"USD","in_stock":true},{"title":"O2 0-25% Vol, AC Power, Local Display","offer_id":48206570520766,"sku":"66-5A02-25-L","price":1839.75,"currency_code":"USD","in_stock":true},{"title":"H2S 0-100 ppm, AC Power, Local Display","offer_id":48206570553534,"sku":"66-5A03-10-L","price":1839.75,"currency_code":"USD","in_stock":true},{"title":"NH3 0-100 ppm, AC Power, Local Display","offer_id":48206570586302,"sku":"66-5A06-10-L","price":1980.0,"currency_code":"USD","in_stock":true},{"title":"Cl2 0-10 ppm, AC Power, Local Display","offer_id":48206570619070,"sku":"66-5A12-10-L","price":1980.0,"currency_code":"USD","in_stock":true},{"title":"HCN 0-15 ppm, AC Power, Local Display","offer_id":48206570651838,"sku":"66-5A05-15-L","price":1387.5,"currency_code":"USD","in_stock":true},{"title":"SO2 0-20 ppm, AC Power, Local Display","offer_id":48206570684606,"sku":"66-5A10-20-L","price":1980.0,"currency_code":"USD","in_stock":true},{"title":"PH3 0-5 ppm, AC Power, Local Display","offer_id":48206570717374,"sku":"66-5A15-05-L","price":2505.0,"currency_code":"USD","in_stock":true},{"title":"HF 0-10 ppm, AC Power, Local Display","offer_id":48206570750142,"sku":"66-5A14-10-L","price":2392.5,"currency_code":"USD","in_stock":true},{"title":"HCl 0-20 ppm, AC Power, Local Display","offer_id":48206570782910,"sku":"66-5A04-02-L","price":2392.5,"currency_code":"USD","in_stock":true},{"title":"H2 0-100% LEL, AC Power, Local Display","offer_id":48206570815678,"sku":"66-5A39-40-L","price":2392.5,"currency_code":"USD","in_stock":true},{"title":"Hydrocarbons (CH4) 0-100% LEL, IR, AC Power, Local Display","offer_id":48206570848446,"sku":"66-5A51-10-L","price":2392.5,"currency_code":"USD","in_stock":true},{"title":"CO2 0-5,000 ppm, IR, AC Power, Local Display","offer_id":48206570881214,"sku":"66-5A54-05-L","price":2392.5,"currency_code":"USD","in_stock":true},{"title":"VOC 10.6 eV PID 0-100 ppm, AC Power, Local Display","offer_id":48206570913982,"sku":"66-5A93-10-L","price":2709.75,"currency_code":"USD","in_stock":true},{"title":"AsH3 0-1 ppm, AC Power, Local Display","offer_id":48206570946750,"sku":"66-5A68-01-L","price":2392.5,"currency_code":"USD","in_stock":true},{"title":"O2 0-25% Vol, AC Power, 2 Relays (No Display)","offer_id":48206570979518,"sku":"66-5A02-25-R","price":1526.25,"currency_code":"USD","in_stock":true},{"title":"CO 0-1000 ppm, Wireless Battery-Powered, 900MHz","offer_id":48206571012286,"sku":"66-5B01-99-W","price":1481.25,"currency_code":"USD","in_stock":true},{"title":"H2S 0-100 ppm, Wireless Battery-Powered, 900MHz","offer_id":48206571045054,"sku":"66-5B03-10-W","price":1481.25,"currency_code":"USD","in_stock":true},{"title":"VOC 10.6 eV PID 0-100 ppm, Wireless Battery-Powered, 900MHz","offer_id":48206571077822,"sku":"66-5B93-10-W","price":2788.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/Air-Alert-Image_436043d9-c888-4ef9-bbd5-0b0c6e94af4d.jpg?v=1785127508","url":"https:\/\/envirotechonline.com\/products\/rki-air-alert-fixed-gas-transmitter","provider":"EnviroTech Services","version":"1.0","type":"link"}
